A gauge for measuring the thickness of a piece of steel or other ferromagnetic substrate. The gauge may be used to measure the wall thickness of tubing, a pipe, a shim, a plate, etc, given that it's made from a material that a magnet might be attracted to. The gauge uses a force sensor to measure the force between a magnet and the tubing, pipe, shim, plate, etc. Because different thicknesses correspond to a different magnitude of force, the gauge may be used to find flaws and variations in the material. The gauge may use a force sensor that is approved for use in or near flammable environments.
